To all 'whom t may concern:

Be it known that we, CHARLEsH. MILLER, a citizen of the United Statea'an'd KNU'r A. READ, a subject of the `King of Sweden, residing at Oskaloosa, in the county of Mahaska and 'State of Iowa, have invented cer tain new and useful Improvements in Hydrants7 of which the following is a specification.

This invention relates to hydrants and has special reference to means for controlling 4the flow of water through the hydrant as it is needed. @ne object of the invention is to provide a hydrant of such construction that a copious flow will be permitted so that the device may be advantageously employed as a l'ire plug. Another obj ectof the invention is to provide efficient means for draining the device of water which might accumulate therein after theflow has been cut o so that damage to the hydrant due to freezing of such accumulated water will be prevented. A still further object of the invention is to provide means whereby when the cut-off valve is opened7 the drain valve will be automatically closed without any particular attention upon the part of the operator.

Other incidental objects of the invention will appear as the description of the same proceeds and the invention resides in certain novel features which are illustrated in the accompanying drawings and will be more particularlyy pointed out in the claims following the detailed description.

In the annexed drawings: Y

Figure 1 is a vertical section. of the lower portion of a hydrant embodying our imj provements;

Fig. 2 is a horizontal section on the line 2 2 0f Fig. l;

Fig. V3 is a transverse vertical section on the'line 3-3 of Fig. 1;

Fig. 4 is a detail horizontal section on the line 4 4 of Fig. Vl;

Fig. 5 Vis a detail perspective view ofv a portion of the casing.

a boot-like casing 1 which is adapted at its upper end tovbe secured to a conduit or hydrant body 2 which will be secured in the ground in any well known manner and is constructed at its upper end (not shown) with the usual outlets. The boot-like' casing 1 constitutes the lower end of the hydrant and is provided with a lateral offset 3 which offset 3 extends into the vertical plane of the main body of the casing 1, as shown at 4, and at the inner end of the offset 3 is a valve seat 5 which may be merely a beveled face formed around the opening which establishes communication with the water main or may be aremovable ring or lining, as illustrated. Depending from the bottom 4 of the casing is a drain spout'G through which any@ water which might .collect within the casing, after the port defined by the valve seat 5 is closed, may escape.

The casing 1 gradually reduces in diameter toward its upper end, as clearly shown in Fig. 1, and one inner wall of the said casing is vertical, as shown at 7. The said vertical wall 7 is disposed in alinement with YVone wall of the body 2 and upon the sides of the casing 1, parallel withthe said wall 7 are ribs S which project toward each other and constitute guides which are engagedl by the gear casing 9 Vto thereby prevent rotation of said casing. Smaller offsets 10 are also provided upon the inner surface ofthe" casing between the ribs 8 and the adjacent wall 7 so that grooves 11 will bev formed to receive the offsetsor lugs 12 upon'the gear casing to further aid in holding the casing in its proper position within the main casing 1. The grooves 11 also receive the ends of the guiding arms 13 upon the drainvalve, as will be presently more fully set forth. The gear casing 9 is constructed in two members disposed one above the other'and firmly securedtogether by bolts 14 inserted 'vertically therethrough, aswill be readily understood. The gear case 9 contains three beveled gears which intermesh and serve to operate the cut eoV 0H valve and the drain valve. The driving Y vthe upper end of the gear case 9 and has an angular yupper extremity 17. A coupling 'n sleeve 18 is secured to this angular extremity In carrying out our invention we employ ing rod. Inasmuch as the mechanism at the upper end of the'V hydrant may be of any iio Well knov:n form and forms no part of our present invention, it is not illustrated in the accompanying drawings but it is thought the manner of manipulating the same will be readily understood by those skilled in the art. The driving gear 15 is a beveled pinion, as shown clearly in F ig. l, and meshes lwith an intermediate beveled gear 2O which ias an elongated hub journaled at its opposite ends in the opposite sides of the gear case 9, as shown at 2l and 22. rl`his hub is internally threaded, as shown at 2S, and receives the threaded spindle 24 of the cut-ott valve. The gear 2O is driven by the pinion 15, as is obvious, and also meshes ivith a beveled pinion 25 which has a hub or spindle 2G journaled in the loiver end ot the gear ease 9 and provided with a threaded extremity 27 depending therefrom to operate the drain valve, as will presently particularly appear. The out off valve comprises a disk or plate 28 which has a central otllset portion Whereiy to torni a socket 29 in its inner tace which is adapted to over the inner projecting end of the hub ot the gear 2G so that the cut ott valve may be Withdrawn from its seat to the greatest possible extent and thereby permit an uninterrupted inlioiv of the Water. The disk or plate 28 is litted upon a smooth cylindrical portion 30 at the end ot the valve spindle and the extremity orP this portion 30 is threaded, as shown at 3l. A rubber or tabric Washer 32 is iitted upon the portion 3() of the valve spindle against the plate or disk y28 and a metallic Washer 83 is placed upon the spindle against the said fabric Washer, a nut 34 being engaged upon the threaded terminal 3l and turned home against the metallic Washer so as to clamp the vvasher 32 lirnily into place. lt Will be readily understood that the washer 32 Will be more or less elastic and tits against tne valve scat 5 so that, when the valve is moved outwardly to its :tull extent, the inflow ot Water will be etlectually cut otl. The disk or plate 28 is provided upon its edge at dia f metrically opposite points With lateral lugs or progections 35 which engage under the short ribs 3G formed on the inner opposite vralls of the casing l so that rotation et the valve Will be prevented and it Will be forced to move in a rectilinear path. At the lovvest point of its edge, the plate 28 provided .vith an additional lug or projection 37 Which is adapted to ride upon a ribV 38 formed longitudinallyy oi the bottom exteng sion 4 ot the casing to further prevent rotation or" the valve. The tloor of the extension 4 of the casing is inclined at opposite sides of the rib 38, as shown at 39, in Fig. 3, and by dotted lines in Fig. l, so that any Water which might tend to collect in the casing Will be directed to the drain spout 6. ln order to permit the fullest possible tloiv of Water when it is needed and to tree the casing as fully as possible ot all projections which might tend to retard or restrict the inflow, the ribs 86 do not extend the full length of the casing but are very short and the valve disk or plate is formed with Wings 40 at opposite sides of its spindle which are adapted to litagainst the opposite sides of, the gear case 9 and thereby prevent rotation of the valve during the interval When. the lugs 35 Will be out of engagement with the said ribs 36.

The drain valve comprises a sleeve or ring 4l which is internally threaded to engage and be supported by the threaded spindle 91'? and this ring, collar, or sleeve is mounted Within a thimble 42 Which is threaded into a shoulder or partition 43 formed on the innery surface ot the drain spout as clearly shown in Fig. l. The sleeve 41 is ot less diameter than the internal diameter of the thimble so that .a space for the passage ot Water vvill be provided between the thimble and the sleeve. The guide arms i3 are formed integral With the upper end of the sleeve 41 and the lower end of the sleeve is provided with a pin 44 upon which the partition 43, Will flow to and throughV the said ports. The spout 6 may be connected in any convenient or preferred manner with the Water main so that this Water will be returned to the main or, if it be desired to guard against the Water from the main backing up in the hydrant, .the drain may be connected `{vith a sewer or any other outlet.

lt is thought the use and advantages of our improved device will be readily understood and appreciated from the foregoing description taken in connection with the accompanying drawings. l/Vhen the hydrant is not in use, the parts will be arranged as shovvn in l, the out ott1 valve being seated and the drain valve being lowered` When it is so as to open the drain'ports.

desired to draiv Water, the operating rod 19 is rotated by means ot'a spanner or other tool applied to its upper end and the rotation of this rod Will be imparted directly to the beveled pinion l5 Which Will direct the actuating gear 20 and through the same transmit rotation to the gear 25. The rotation et the gear 2O Will, through the enga gement ot the hub With the threaded spindle 27, witht the cut off valve from its seat so that the inlet port ivill be uncovthe drain valve will be raised so that the,

disk or washer Ll5 will be brought over and above the drain ports ai and, consequently, the' water cannot escape through the said ports but will be held within the casing. `When the cut off valve is fully withdrawn, a large clear passage for the water will be established and the water will flow rapidly and in a large volume into the body 2 and rise through the same to the outlet pipes. lt will, of course, be understood that the threaded spindles 211 and 27 will be so relatively proportioned that the drain valve will have a more limited movement than the cut off valve so that, while the cut olf valve will move rapidly and over a relatively long path7 the drain valve will move very slowly and over a relatively short path so that while the drain valve will have sufficient movement to cut 01T the iow through the drain ports, its movement will not be so eX- tensive as to require the provision of a long drain spout or entail unnecessary weight and bulk in the lower portion of the casing. The guide arms 13 not only cause the drain valve to move steadily when it is being opened or closed but also serve to prevent rotation of the said valve and, consequently, compel it to move in av rectilinear path. y

Our device is exceedingly simple in the construction and arrangement of its parts and by the peculiar formation of the casing ample accommodation for the gearing is provided. The gearing will be positively operated so that the valves will be moved easily to be opened or closed. The engagement of the parts and the form of the casing facilitates the assembling o-f the mechanism so that the casing 1 which forms the lower end of the hydrant may be set in position and connected with the water main either before or after the valves and the operating gearing are placed within the same. lVhen the cut off valve is fully withdrawn it will lie entirely within the area defined by the upper end of the casing and will be between the ends of the ribs or the shoulders 36 and the gear case 9. If, therefore, the cut olf valve be assembled with the other parts in the same relative position it will occupy when the How of water is permitted, the entire assembled mechanism may be inserted through the upper end of the casing and moved downwardly to the operative position, the ends of the guide arms 13 and the projections 12 engaging the groove 11 and thereby guiding the parts in vtheir downward movement. rlhe gear case 9 is provided with grooves or notches which engage the rib 8, as shown clearly in Fig. 2, so that the proper positioning of the valves and the gearing within the casing will be positively insured. Of course, if any repairs should become necessary, the parts may be removed in the reverse manner. After the casing has been placed in position and the gear case 9 with the valves has been lowered into the casing, the operating rod 9 is inserted so that its lower end will engage the coupling 18 which is then fastened to the rod in any preferred manner. The described operation of assembling the parts will be readily understood upon reference to the dotted lines in Figs. 1 and 2 which indicate the open position of the cut-off valve.

1. In a hydrant, the combination of a casing having an inlet port in its side and pro-V vided with laterally extending gui'des adjacent the port, a valve to open or close said port and constructed to engage said guides, and means for moving the said valve laterally to or from the'inlet port, the range of movement of the valve exceeding the extent ofthe said guides whereby when the valve is fully opened, it may bemoved across the endsV of the guides and withdrawn from the casing with the operating mechanism.
